2-Pack Universal Mag Carrier IWB/OWB Magazine Holster Fit: 9mm/.40 Double Stack Magazines

Fit nice and snug to the belt. You can adjust the tension on the retention, so that is nice. Hold the mags perfectly for me.

Works well. Inexpensive. Good retention. Fit Glock and Walther mags without issue. I use them for training and matches. No issues with retaining mags.

P365: Stable but wider than needed. With the adjustment, P365 mags fit with good retention, but there's an extra 3/8 inch of space that's not needed. If you're wearing IWB, I'd look for something thinner for P365. The adjustment is easy, just turning a set screw until 2 edges of the mag bind. The V-shaped edge of the carrier keeps the mag centered so it doesn't flop around. There's a review showing that it's too narrow for P365 mags, but that photo looks like he ended up with a single stack mag. Probably just received the wrong product.

Great product and great price, fits prefectly my 9mm glock 45 double stack mag (17 rounds)

I really like these mag carriers. Great adjustability for different mag types. Very high quality.

These work fine for my double stack G19 Mags. If I had to find a flaw, the belt grab is a bit too much and they are difficult to get off at the end of the day. I have the bumper torqued to where I'm comfortable at the retention and release point. Really just a no name brand that cost's half of what one with a logo on it would. Good value here if your looking for functionality over looks.

Holds your magazines secure I wish they just a little deeper for larger capacity mags.

Will work in a pinch. Retention is iffy and the whole thing is pretty bulky for iwb.
